With this post, we now pronounce the Flaming Lips “Kings Of The Soundtrack.” Makes sense for the cinematic Oklahoma troupe to lend their music beyond standard music/video stuff (see also: Yoshimi Battles The Theater Critics), but since releasing At War With The Mystics a year-and-a-half ago, it’s been mostly film fare for the Flaming ones, including “The Supreme Being Teaches Spider-Man How To Be In Love” for the Spidey 3 OST and “I Was Zapped By The Lucky Super Rainbow” for the Dane Cook/Jessica Alba flick Good Luck Chuck‘s soundtrack.

Now we’re pleased to announce the Lips are leaving Dane Cook for Ben Stiller in The Heartbreak Kid, which is, at least, a step in the right direction. As the title suggests, “The Tale Of The Horny Frog”‘s got a kids TV/Sesame Street vibe, though the frog-hop’s an adult metaphor; we’re imagining a video featuring a bunch of lip-syncing puppets and a wink to the old-timers. The clippity-cloppity shuffle’s a sunny and sweet one, perfect for a rom-com and hand-held walks on happy days. Aside from the exasperated “Fuck!” at the end.
